Explanation:

船闸红灯的含义

在航海和船闸操作中，信号灯用于指导船只安全通行。红灯通常是全球通用的“停止”信号。在船闸（lock）处，红灯意味着船只必须停止，不得进入船闸，并应注意观察是否有正在驶出的船只，以避免碰撞。这属于Boating Safety（航海安全）的基本常识。

离岸前的准备工作

在离开码头（leaving the dock）之前，为了确保航行安全，驾驶员应当进行系统性的安全检查。检查预备离岸清单（pre-departure checklist）可以确保所有安全设备（如救生衣、灭火器）齐全，船只状况良好，且乘员了解安全须知。这同样是Boating Safety中非常关键的一环。
